General Description
AH280 is the integrated Hall sensor owned two complementary outputs for motor’s coil driving, auto locked shutdown and auto restart functions. Functional block diagram includes that a regulator with temperature-compensated band-gap, an on-chip Hall voltage generator, a comparator, a Schmitt trigger and two current output drivers. The regulator can provide wide operational voltage range. The Hall voltage generator is to amplify the Hall voltage due to Hall effect. A Schmitt trigger is to provide switching Hysteresis for noise rejection.

- On chip Hall plate 
- Built-in Zener diode protection for output driver
- Built-in protection diode for power reverse connecting
-Rotor-lock detection
-Automatically restart after release of motor locking
- Adjustable auto restart time
- Operating voltage: 3.5~20 V
- Max Output current: IO(AVE)= 500mA
- Packages: SIP-5L, SOP-8L, SOP-8L EP
- Less external component
